Move over humans, technology is taking over the trading floor. Algorithmic trading—also known as “algo trading”——makes trading securities both simpler and complex at the same time. The use of bots has grown manifold with advancements in AI and computing power. Like it or not, high-frequency trading is here to stay. Let’s dig in.
What is an algorithmic trading bot?
Trading algorithms are computer programs that can execute trades at split-second speeds. An algorithmic trading bot is basically a code that makes trading decisions that humans would have otherwise made. The bot can spot buy and sell opportunities and can mark entry and exit positions too. Robots that work as algorithmic trading bots can generate profits at great speed and accuracy—-levels that humans find nearly impossible to attain.
Why should you opt for algorithmic trading?
There are several reasons why you would choose algorithmic trading bots:
Speed and efficiency: Bots can analyze market data and execute trades much faster than humans, allowing you to take advantage of short-term market movements and make decisions much faster.
Buzzing without a break: While stock markets operate in trading cycles only, crypto markets are open 24/7. In this case, algorithmic bots can monitor and trade the markets continuously, even when you have to sleep or eat.
Scalability: Bots are codes, and codes are infinitely scalable. They can accurately match the needs of the trader and adjust strategy to resonate with what they want to achieve with their capital.
Bots store historical data: Bots can always be backtested, which means that they can record what decisions they took and why. Analyzing patterns can help traders understand the algorithmic strategy and give them the ability to modify their responses.
How algorithmic trading works
Algorithmic trading in security markets uses algorithmic trading bots to analyze market data and execute trades based on predefined rules and algorithms. The bots can be programmed to track market indicators, such as price, volume, and order book depth, and make trades based on specified criteria.
How the bot operates
For example, a bot may be programmed to buy BTC when its price falls below $20,000, for instance, and sell it when it rises above $25,000.
The algorithmic trading bot, in this case, would monitor BTC prices across various platforms to immediately buy/sell when the time arises. Algorithmic trading bots also take the emotion and euphoria out of trading, operating solely based on how it’s been programmed.
At this point, traders often have to program these bots to reflect their specific goals. The process can involve a lot of trial and error, including some errors in judgment.
Algorithmic trading strategies
Algorithmic trading bots use strategies to reduce workload for you, the trader, and to maximize profitability by leveraging speed and accuracy. Here are some of the strategies used.
Arbitrage involves buying an asset in one market/exchange and selling it in another for a profit. Opportunities for arbitrage cannot have room for error, so algorithmic trading bots can use code to execute these trades immediately with perfection. Arbitrage trading also means monitoring different platforms, factoring in trade fees, and making accurate orders—-all at the same time. Algorithmic trading bots outperform humans on all these fronts.
Index fund rebalancing
Index funds usually place bets on the movements of major indices like NIFTY in India or the S&P 500 in the United States. However, to constantly keep making profits, they must keep rebalancing their capital allocations to multiple companies—–selling some and buying some all the time. Algorithmic trading bots execute these rebalancing decisions, which help traders to achieve their goals without having to do the tough math.
Backtesting and optimization
Backtesting and optimization for an algorithmic trading bot involve using historical market data to evaluate the performance of a trading strategy before it is executed live in the markets. The process usually involves:
Analyzing collected historical data: Including price, volume, and other relevant market data.
Developing a specific trading strategy: Includes defining the rules and algorithms the bot will use to make trades, such as entry and exit price levels, position sizing, and proper risk management.
Backtesting the strategy: The process usually involves simulating the trading strategy using collected information and evaluating the bot’s performance based on profit, loss, and risk-adjusted returns.
Optimizing the strategy: This involves adjusting the rules and algorithms of the bot to improve its performance based on data collected during backtesting. It is here that a well-defined trading strategy can come in handy.
It is important to note that backtesting and optimizing an algorithmic trading bot is an iterative and dynamic process. Traders usually have to go through multiple rounds of testing and optimization before they are satisfied that the code will perform as expected in the real world. Past performance is not necessarily indicative of future results, and even after extensive testing, traders have to operate with an assumed margin of error.
Live execution is usually the last step of using an algorithmic trading bot. At this stage, backtesting, optimization, and planning combine to bring real-world results. Bots are tested for their adaptability to different market phases, and involving various asset classes.
Are trading bots profitable?
Trading bots can be programmed to fit your specific strategy keeping in mind your capital availability and risk appetite. While nothing can be absolutely accurate all the time, bots can certainly make trading easier.
How do I make a bot for algorithmic trading?
Yes, it is possible to create a trading bot to suit your requirements. However, there are also standard bots available that you can customize to meet your specifications.
Do AI trading bots exist?
Yes, some of them are Stock Hero, Scanz, and Equbot.
